About

chDB SQL Shell is a browser-based SQL interface powered by chDB, an embeddable ClickHouse engine that runs entirely in-browser via WebAssembly. It lets you run ClickHouse-compatible SQL queries directly in your browser without any server setup. You can import data and explore it instantly using familiar SQL syntax.

What it can do

  • Execute ClickHouse-compatible SQL queries in the browser

    SQL query text → Query results displayed in the browser

  • Import and load data for querying

    Data file (e.g., CSV, Parquet, or other supported formats) → Queryable dataset available in the SQL shell

  • Run an embedded ClickHouse engine without server setup

    User-initiated session in a web browser → Fully functional ClickHouse SQL environment running locally via WebAssembly

  • Explore and analyze datasets using SQL

    Imported data and SQL SELECT statements → Filtered, aggregated, or transformed data results

  • Perform in-browser data analysis without sending data to a server

    Local data and SQL queries → Query results processed entirely client-side

  • Query structured data using familiar SQL syntax

    Standard SQL statements (SELECT, WHERE, GROUP BY, etc.) → Structured result sets matching the query criteria

Why it made the leaderboard

If you want to explore ClickHouse's powerful OLAP SQL dialect without installing anything or signing up for a cloud account, chDB SQL Shell runs the full engine in your browser via WebAssembly. It's the fastest path from 'I have a CSV' to 'I have analytical query results' using ClickHouse syntax — no server, no Docker, no account required.
